CVE-2023-54352

Estado: AplazadaCrítica (9.3)—

WordPress Seotheme contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by uploading malicious files to the theme directory. Attackers can access the uploaded PHP shell at /wp-content/themes/seotheme/mar.php to execute system commands and upload additional files for persistent access.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad remota sin autenticación en aplicación web (AV:N, PR:N, UI:N) permite carga de archivos maliciosos y ejecución de código PHP arbitrario con acceso a shell persistente.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
